enum-map-derive

New features

• It's now possible to use return and ? within macro_rules! macro.

• Enum trait is much simpler having two methods only.

Other changes

• Removed previously deprecated features.

• Renamed to_usize to into_usize matching the naming convention used in Rust programming language.

Incompatible changes

• Now requires Rust 1.36.

• Fixed the issue where an aliasing From trait implementation caused compilation errors with enum_map! macro.

Incompatible changes

• Now requires Rust 1.31.

New features

• Default serde features are disabled. This allows enabling serde feature when compiling without std.

Change of #[derive(EnumMap)] to #[derive(Enum)] was supposed to appear in 0.3.0, but it was forgotten about. This release fixes just that.

Incompatible changes

• Changed #[derive(EnumMap)] to #[derive(Enum)] to match trait name.

New features

• Implemented compact serde serialization for binary formats like bincode.

• Iterator traits with exception now implement FusedIterator.

Incompatible changes

• Increased required Rust version to 1.26.0.

• Renamed Internal trait to Enum.

• Added new associated constant POSSIBLE_VALUES to Enum trait, representing the number of possible values the type can have. Manual implementations are required to provide it.

• Removed Enum implementation for Option<T>.

• Implemented compact serialization, for formats like bincode. This makes it impossible to deserialize non-compact representation used by enum-map 0.2.0.

• values method returns Values<V> as opposed to slice::Iter<V>.
